S15·E61 Trade Off

Deakin is furious when Carver and Rickman blow an OBBO to arrest a major dealer. Furious at constant put-downs by his former CID colleagues, Carver decides enough is enough and accepts an offer from an old friend to manage security at his nightclub. In the meantime, Deakin demands Carver track a former informant linked to their target, and after being arrested in possession of heroin by Rickman, tells her about an armed robbery. However, Deakin is further infuriated when the robbery goes down at the wrong bank, so Rickman and Carver arrest their informant once again in possession of heroin. Offering him rehab so he can reunite with his wife, Carver makes a breakthrough, but he gets a personal blow when he misses out on the security manager job. Slipping into a depression, Carver turns to drink to deal with his problems.
